JETSCAPE: Jet Energy-Loss with a Statistically and Computationally Advanced Program Envelope

The Jet Energy-loss Tomography with a Statistically and Computationally Advanced Program Envelope (JETSCAPE) collaboration is an NSF funded multi-institutional effort to design the next generation of event generators to study the physics of jets within the quark-gluon plasma created in ultra-relativistic heavy-ion collisions. Integrated advanced statistical analysis tools provide non-expert users with quantitative methods to validate novel theoretical descriptions of jet modification, by comparison with the complete set of current experimental data. To improve the efficiency of this computationally intensive task, the collaboration has developed trainable emulators that can accurately predict experimental observables by interpolation between full model runs, and employ accelerators such as Graphics Processing Units (GPUs) for both the fluid dynamical simulations and the modification of jets. This framework exists within a user-friendly envelope that allows for continuous modifications, updates and improvements of each of its components.
